An electrocardiogram (EKG) produces a graph showing the electrical impulses of the heart's contracti â¦ ons. It shows various wave forms of the electrical strength and pattern.
These electrical signals are sent to the ECG machine, where they are processed, and printed out as an âECG tracing.â The electrodes are then removed. The ECG test takes less than 5 minutes to perform. What Does the ECG Tracing Look Like? The picture on this page shows a typical, normal ECG. The electrical signals generated from the ten electrodes have been processed into 12 âviewsâ of the heartâs electrical activity - the so-called 12-lead ECG.
